Re: So? - Addendum
Maybe the key thing to having an OS that "people recognize" is having your new OS actually being recognizable as the same OS?
And making an OS "easy to use" might involve having, I dunno, a single place for settings, a single application style , obvious icons for performing tasks rather than expecting people to click and prod the edges of the desktop.
Linux window managers now bear much more resemblance to windows 7 than windows 10 does at this point.
But in any case, ChromeOS is apparently what is being given to kids in US schools now, so presumably that will be what the future spenders there are familiar with...unfortunately this means Google will also be familiar with them.
